Amazon blew past Wall Street expectations for its third quarter earnings as the company’s stock spiked more than 7 percent in after-hours trading Thursday.

Operating expenses came in at $ 43.4 billion, up from $ 32.1 billion from the year-ago quarter. On an earnings call with reporters, Amazon CFO Brian Olsavsky noted that the company continues to invest heavily in Amazon Web Services (AWS); adding benefits for Prime members; the company’s devices like Echo and Fire TV; and expanding its fulfillment center footprint.

Amazon reported $ 1.3 billion in net sales and $ 21 million in operating income from Whole Foods for the quarter (after the Aug. 28 acquisition). Whole Foods posted $ 3.7 billion in sales for the July quarter.

Olsavsky said that Amazon and Whole Foods are now “fully working together.” He noted that Amazon has started to begin the “technical work to make Prime the Whole Foods customer rewards program at some point in the future,” echoing what fellow exec Jeff Wilke said at the GeekWire Summit earlier this month.

Another big Amazon storyline from the quarter was its HQ2 announcement, which sent cities across North America scrambling in an attempt to host the company’s second headquarters and 50,000 new jobs.

Amazon also debuted several new Echo devices, including a new version of its flagship voice speaker. Amazon CEO Jeff Bezos focused on Echo and the company’s voice assistant Alexa in his earnings release statement:

“In the last month alone, we’ve launched five new Alexa-enabled devices, introduced Alexa in India, announced integration with BMW, surpassed 25,000 skills, integrated Alexa with Sonos speakers, taught Alexa to distinguish between two voices, and more. Because Alexa’s brain is in the AWS cloud, her new abilities are available to all Echo customers, not just those who buy a new device,” Bezos said in a statement. “And it’s working — customers have purchased tens of millions of Alexa-enabled devices, given Echo devices over 100,000 5-star reviews, and active customers are up more than 5x since the same time last year. With thousands of developers and hardware makers building new Alexa skills and devices, the Alexa experience will continue to get even better.”
